Liquid degredation detection device, has liquid fed through flow channel configured for gradual blockage by soil components

摘要

The device (20) has a test channel supplied with the test liquid from a collection container, configured so that it becomes blocked by the soil components in the test liquid and a variable volume chamber (47), with measuring of the time taken for the chamber to be increased in volume from its minimum value to its maximum value by the liquid flowing through the test channel for a number of repetitive cycles.
